Mac3 Sequencer is a DIN rail mounted device which balances the run-time of 2 or 3 pumps depending on model in a duty-standby/assist configuration.
Pumps are alternated during normal usage, but allows the controller to activate both pumps together if there is a sudden demand.
The Sequencer can be deployed with a single pressure switch and float switch, or with two pressure switches and a float switch. The twin pressure switch solution allows the one pressure switch to function for regular pump control, while the second acts as an‘emergency switch’ allowing both pumps to be activated together when demand cannot be met by a single pump.

The sequencer is available in different models:

• Sequencer – In rail mounted device which balances the run-time or 2 pumps in a duty-standby/assist configuration.
• Sequencer 2 – Is has the same characteristics and functionality as the sequencer with the added LED’s for visualising faults.
• Sequencer 2q – It has the same characteristics and functions as the sequencer with the addition of a panel containing two switches for pump operation and seven LED diodes that always show the system status.

Note: The above models Tare with either 24Vac or 110/230Vac supply (no 24vdc version is available) – please see brochure. They provide pressure/level switch inputs at 2vac and optional float switch at 24vdc to enhance safety.

• Sequencer 3 – Advanced version of the sequencer that drives groups up to 3 pumps. Interface with LED’s and control buttons.

Advantages

• Pumps are alternated during normal usage, but allows the controller to activate both pumps together if there is a sudden demand.
• Emptying or Filling functions.
• DIN rail mounted device.

Benefits

• Ideal for OEM integration or control panel building
• Alternately Chooses Between 2 Connected Pumps (Pump Alternation) When an Input Switch is Closed
• Duty Assist Input Activates Both Outputs Simultaneously
• Can be used with Pressure or Level Based Controls
• 24V and 117-230V versions

Mac3 Sensopress is a programmable, DIN rail mounted level controller and is ideal for integration with OEM and panel built products.

Sensopress measures the level of liquid in a tank or reservoir using a high accurate pressure sensor which detects the weight of fluid above it. Pumps and valves can be controlled to fill, empty or maintain levels by Sensopress based on the reading of a single sensor with no mechanical movement.

Sensopress avoids the need for technicians to accurately set floats or sensors at various heights within the tank in order to operate pumps and valves at the right levels. All levels and functions can be precisely set from the control panel.

Sensopress can function with any liquid using a probe and can be manually calibrated to accept probes of different ranges.

Sensopress is available in single channel and multi-channel models. The single channel model is supplied with a single output for controlling one external appliance, whereas the multi-channel is supplied with 4 outputs.

Each output channel operates independently and may overlap in range.

Advantages

The supplied level sensor is suitable for clean water and liquid food products. However, Sensopress can function with any liquid using either an alternative probe and can be manually calibrated to accept probes of different ranges.

Benefits

• DIN rail mounted.
• Ideal for OEM systems and panel building.
• Measures level by pressure sensing
• Change all level settings from the control panel
• Available with 1 or 4 outputs
• Suitable for use in clean water or liquid food products

For home (domestic) header tank boosting or in-line boosting of low mains water pressure.

Pump control for pressure boosting by pressure and flow detection. The pump starts by pressure/flow sensing and the pump is stopped by flow sensing. When either water flow or a pressure drop is detected, the E-Control engages the pump to maintain pressure in the system until it detects that the flow has stopped when it disengages the pump.

Clean water only.

Advantages

Simple on-pipe installation with easy to read LED panel.

The E-Control features dry run protection with a warning light on the control panel to show if there is a system error. Also featured is a ‘Anti-lock’ feature. This anti-lock feature prevents a pump from pump from becoming blocked by starting the pump once every 24 hours, preventing small amounts of sediment from settling inside the pump and causing it to fail, and rotating the shaft ensuring adequate lubrication of the seals.

Benefits

• 1″ (25mm) BSP in-line fitting
• Built-in dry-run protection
• Vertical or horizontal Mounting
• Monitors flow and pressure
• Pump anti-lock/anti-blocking cycle

DIN rail-mounted unit, that measures a rainwater tank level using a submerged pressure sensor (not included) and either tops up with a measured amount of mains water (direct systems with submerged pump), or opens a 3-way motorized valve (indoor break tank & pump systems) when required.

When a low-level threshold is reached, RainControl opens a solenoid or motorised valve to supply mains water until a high-level threshold is reached. After this, RainControl de-activates the output and reverts to level display mode.

Advantages

An anti-blocking timer function allows the valve to be scheduled to open periodically regardless of the tank level, to prevent jamming.

All of the thresholds for high and low water levels can be set by the installer, calibrating the unit to whatever installation the unit is connected to.

Benefits

• DIN rail mounted.
• Ideal for OEM systems and panel building.
• Customisable operating parameters.
• Accurate LCD level display and mains cold water top-up/back-up function.
• Level measurement by submerged pressure sensor (not included).
• No moving parts.
